Patented Sept. 19, 1905.

Application filed December 23, 1904. Serial No- 238,154:-

To aZZ whom it may con/eerie:

Be it known that I, D vro GENESE, a citizen of the United States, residing at Baltimore, in the State .of Maryland, have invented new and useful Improvements in Chemical Apparatus,

- which require a certain degree of heat to cause such reduction, but which cannot vbe maintained at such degree of heat for any considerable length of time without decomposing or evaporating, and yet must be kept above a certain temperaturelower than that necessary chemical substance or substances are kept in venient manner for such application as may be required.

While the invention is intended for such general purposes as indicated, the apparatus herein described is more especially intended for use in solidifying mentho-glycerin, glycothymolin, or similar compounds containing such ingredients as menthol, thymol, oil of eucalyptus, and alcohol, all of which ingredicuts are highlyvolatile, besides resinoussubstances which will coagulate if overheated and evaporate if the heat necessary to produce the fluid condition referred to is maintaine A still further object of the invention is to provide for agitating the mass during and after admixture of substances forming the compound and just before the .mass is drawn off and permitted to solidify, which operation prevents d eposit of any of the ingredients while maintained in a heated condition, but at 5 a relatively low temperature.

- In'order that the invention may be clearly thereof.

'water-gage4 and draw-ofl cock 5.

understood, I have illustrated the same in the accompanying drawings, in which Figure '1 is asectional elevation of the main heating device. Fig. 2 is a top plan view of thesame. Fig. 3 is a view, partly in elevation and partly in section, of the secondary heating device, herein referred tofor convenience as the mixing device. Fig. 4is atop plan view,

partly in section, of the mixing device; and

Fig. 5 is aview showing the devices illustrated in Figs. 1 and 3 connected to form the co plete apparatus. i

I will first describe themain heating device I with reference to Figs. ,1, 2, and r).

1 indicates a boiler, whichis designed to be placed upon any suitable heating device, such as illustrated by 2, and is provided with a steam-dome 3 of considerably less diameter than the boiler proper and rising vertically from the central portion of the upper side The boiler 1 is provided with a Supported upon the boiler 1 and surrounding the steam- .dome 3 is an annular chamber 6, which is about half the height of the steam-dome 3' and is provided in its upper side with a closable filling-orifice 7. The chamber 6 is provided toward its lower endwith draw-off cocks 8, preferably three in number, arranged at equal distances apart around the circumference of the said chamber, by means of which the substance \contained in such chamber may be drawn off when required. Supported upon the annular chamber 6 and arranged to encircle the steam-dome 3' are threesegmental chambers 9, each of which is provided with a draw-off cook 10 toward its lower end. The steam-dome 3 is provided in its upper end with a closable filling-orifice 11, by means of which water may be supplied to the boiler 1, and with a central outlet-pipe 12, on which is mounted a screw-threaded thimble 13,v by

means of which a pipe 1% may be connected to and communicate with said steam-dome. The pipe 14 is connected at its other end to and communicates with a steam-chamber 15,

forming a part of the mixing device, before two short steam-ducts 16, each of which is I secured to the outer wall 17 of a steam-jacket 18, the inner wall of which is indicated by 19. It will be understood that the ducts 16 communicate, through the outer wall 17, with the space 20 between the two walls 17 and 19. The jackets 18 are cup-shaped and are open at their top and bottom, the bottom opening 21 being, however, much smaller than the opening in the top. Supported in each of the steam-jackets 18 is a cup 22, having an upper flanged edge 23, which is adapted to rest upon the top of the steam-jacket. Secured in the lower end of each of the cups 22 is a short outlet pipe or tap 2 1, having a valve 25, the lower portion of the cup and said tap, with its valve, extending through the opening 21 in the lower end of the steam-jacket. Preferably I employ a removable handle 26 for turning the valve 25, so as not to interfere with the removal of the cups from the steam-jackets. The cups 22 are designed to nest snugly within the steam-jacket, and as the steam from the steam-chamber 15 can circulate freely in the space 20 surrounding said cups it will be obvious that the contents thereof can be heated, while at the same time the steam will not be brought into contact with the ingredients of the cups. Mounted on opposite sides of the steam chamber and at the upper end thereof are two brackets 27 each of which has preferably one of its faces serrated.

28 indicates an arm having one of its sides serrated at one end'portion, and the bracket 27 and the said serrated end portion of said arm are apertured to receive a bolt 29, on which is mounted a clamping-nut 30, by means of which the arm 28 may be firmly secured to the bracket 27. It will be understood that the arm 28 is in a similar manner secured to each of the brackets 27. Formed on the outer end of each of the arms 28 is an elongated bearing 31, through which passes a shaft 32, having on its upper end a pulley 33, said shaft being prevented from rising by means of a collar 34 hearing against the under edge of the bearing 31 and clamped to the shaft by means of a screw 35. 'The lower end of each shaft 32 is supported in a spider bearing 36, and

- mounted on the lower end portion of each shaft are a series of agitator-blades 37. By means of bands applied in the ordinary way to the pulleys 33 it will be seen that the shafts 32, with their agitator-blades 37 may revolve, so that the'miXture in the cups 22 may be thoroughly stirred or agitated. The steamchamber 15 is provided with a gage 38 to indicate the height of the water condensation therein, said gage having a draw-off cook 39. From the top of the steam-chamber 15 leads an escape-pipe 4:0.

It will be seen that the pipe 14:, connecting the heating device and the mixing device, is for the purpose of conducting steam from the steam'dome 3 to the interior of the steamchamber 15 for the purpose of supplying steam, and consequently heat, to the jackets 18. In the use of the apparatus 1 tirst place in the annular chamber (5 the materials to be liquefied, which in the example named would be stearic acid, glycerin, and carbonate of soda, and subject this mixture to a temperature of about 220 Fahrenheit for front three to live hours, the compounds indicated forming the solidifying base of the solid ultimately to be produced. The liquid, having about the consistency of wine, may be at oncedrawn oil from the cocks 8, and if for any reason the liquid produced cannot be at once utilized it may be drawn oil into the chambers t), which have removable tops 11 for this purpose, which chambers will maintain liquid at the temperature of about 150*, which is a sutiicient degree of heat to preserve the lluid condition, and yet not great enough to produce decomposition. It will be understood, however, that the chambers 9 are only for convenience in case the operator is not ready to at once use the stearate of glycerin as soon as it is drawn from the chamber e. The steal-ate of glycerin is next poured into the cups 22, which are maintained by the steam-jackets at a temperature of about 125 l ahrenheit, and the glyco-thymolin or mentho-glycerin are then added thereto. The mixture is thoroughly agitated by the blades 37, and as soon as the ingredients are thoroughly lmixed the resultantcompound is drawn oti' through the tap 2 1 into suitable molds and allowed to solidify. The temperature of the cups 22 is sutiicient to convert the mixture into low-fusing lluid, but will not cause any of the essential-oils to be evaporated. Itapidity of operation is necessary, as the mixture described solidities very quickly, and hence the taps provided in the bottom of the cups 22 atlord a most convenient means for readily withdrawing the compound. There is therefore no interval of delay in the operaton such as would be necessitated by removing the cups from the stean'i-jaekets and pouring the contents out of the same. Furthermore, the provision of the taps in the bottom of the cups assures absolute cleanliness in the operation. To remove the cups for the purpose of cl iansing the same at the completion of the operation, the screw 35 is loosened and the shaft 32 raised to carry the agitator 37 out of the cups. Then the clamping-nut 30 is loosened and the arm 28 turned upward, carrying the shaft and agitator out of the way, when the cup can be readily removed.

Having thus fully described my invention, what I claim as new is 1.
